NASA to launch world’s first mission to Sun in 2018

WASHINGTON: NASA will launch the first global mission in the sun next year, which will explore the atmosphere of our star and answer questions about solar physics that have intrigued scientists for more than six decades.
The Solar Probe Parker was named in honour of pioneering astrophysicist Eugene Parker, who predicted the existence of the solar wind that is near 60 years, announced yesterday the American space agency.
“This is the first time NASA has named a spacecraft a living individual,” said Thomas Zurbuchen, associate director of the NASA Science Mission Directorate.
The spacecraft, the size of a small car, is responsible for great technological advances that will solve many of the great mysteries about our star, including why the sun’s crown is much hotter than its surface.
Parker Solar Probe cross the Sun’s atmosphere, near the surface than any spacecraft before, in view of the brutal conditions of heat and radiation, and finally, provide the closest observations of humanity a star, said the POT.
To carry out this unprecedented research, spacecraft and instruments will be protected from the heat of the sun by a carbon shielding compound 4.5 inches thick.
The spacecraft is to be presented in a 20-day window that will begin on July 31, 2018, from NASA’s Kennedy Space Center in Florida.
“Solar Probe is a region of space that has never been explored before,” said Parker, a professor at the University of Chicago in the United States.
“It’s very exciting that we’re finally going to look at it.” “We would like to have more detailed measures of what is happening in the solar wind, I’m sure there will be surprises,” Parker said.
In the 1950s, Parker proposed a number of concepts about how stars – including our Sun – emit energy.
He called this cascade of solar wind energy and described a whole complex system of plasma, magnetic fields and energetic particles that make up this phenomenon.
Parker also theorized an explanation of the superheated solar atmosphere, the crown, which, contrary to what was expected from the laws of physics, was warmer than the surface of the Sun itself.
Many NASA missions have continued to focus on this complex space environment defined by our star – a field of research known as Heliophysics.
“Parker Solar Probe answer the questions of solar physics that intrigued over six decades,” said Nicola Fox, scientific scientist Parker Solar Project Johns Hopkins University.
